环境: Sun Fire V120 安装Solaris10 启用两个网卡
eri0 接 192.168.0.254 做内网NAT主机用
eri1 接 192.168.10.2 (公司外网,光纤接入后通过路由器,接到交换机上,网段192.168.10.x ,给内网用NAT主机是外网局域网中的一台机器)

现在的问题是:
(1) 不能通过路由器 192.168.10.1 网段上网, 使用 nslookup 可解析域名
# nslookup www.baidu.com
Server: 192.168.10.1
Address: 192.168.10.1#53
Non-authoritative answer:
www.baidu.com canonical name = www.a.shifen.com.
Name: www.a.shifen.com
Address: 202.108.22.5
Name: www.a.shifen.com
Address: 202.108.22.43
# ping www.baidu.com

no answer from www.baidu.com
(2) 如何设置 NAT 使内网(192.168.0.X) 的客户端能上网?
请高手协助解决,不胜感激. |
